A senior Iranian official says implementation day for Tehran's historic nuclear deal with six world powers will not go beyond this weekend. “The affairs are under way at a high pace and the latest details are being finalized today or tomorrow and it (implementation) will not be later than Saturday or Sunday," Iran’s deputy foreign minister, Abbas Araqchi, who was also a top nuclear negotiator at talks with the P5+1 group of countries, said Wednesday.He said that Iran's Foreign Minister Mohammad Javad Zarif and EU Foreign Policy Chief Federica Mogherini are expected to issue a joint statement on the implementation of the Joint Comprehensive Plan of Action (JCPOA), reached between Tehran and the P5+1 group in mid-July last year. The P5+1 comprises the United States, Britain, France, China, and Russia plus Germany.Under the JCPOA, limits are put on Iran’s nuclear activities in exchange for, among other things, the removal of all nuclear-related economic and financial bans against the Islamic Republic.Araqchi, who heads Iranian Foreign Ministry’s committee following up on the implementation of JCPOA, further said that the International Atomic Energy Agency (IAEA|) is expected to issue its “final” report on Iran’s fulfillment of its commitments under the JCPOA by Friday.The IAEA's Board of Governors passed a resolution last December, which brought an end to a 12-year investigation into the past and present outstanding issues regarding Iran’s nuclear program.Following the vote, the IAEA chief, Yukiya Amano, told reporters that Iran has been implementing restrictions on its nuclear activities at “high speed.”Meanwhile, expert-level talks are currently underway in Vienna between representative of Iran and the P5+1.Hamid Ba'eidinejad, the director general for political and international security affairs at Iran's Foreign Ministry, heads the Iranian delegation to the talks.Foreign ministers of Iran and the six powers are likely to meet next week.
